Strong enhancement of chlorophyll a concentration by a weak typhoon

, 2010
Recent studies demonstrate that chlorophyll a (chl a) concentrations in the surface ocean can be significantly enhanced due to typhoons. The present study investigated chl a concentrations in the middle of the South China Sea (SCS) from 1997-2007.

Accounting for ALA Natural Mutations Enhances the Efficiency of Graphene Oxide Nanopriming in Bar‐Modified Arabidopsis

Advanced Science, EarlyView.
Nanopriming enhances plant resilience to environmental challenges; however, its effectiveness across diverse genetic backgrounds, including genetic modifications and natural variations, remains uncertain. These findings demonstrate that nanopriming improves efficacy when natural genetic variations are considered, particularly in genetically modified ...

Revisiting chlorophyll extraction methods in biological soil crusts – methodology for determination of chlorophyll a and chlorophyll a + b as compared to previous methods

, 2017
. Chlorophyll concentrations of biological soil crust (biocrust) samples are commonly determined to quantify the relevance of photosynthetically active organisms within these surface soil communities. Whereas chlorophyll extraction methods for freshwater

Manipulating the Light Systemic Signal HY5 Greatly Improve Fruit Quality in Tomato

Advanced Science, EarlyView.
This study establishes that HY5, activated by low‐dose light, acts as a systemic signal to enhance tomato fruit quality by directly promoting carotenoid synthesis and sugar metabolism. These findings demonstrate HY5's mobility from leaves to fruits and its application potential through nighttime LED lighting, offering a practical strategy for crop ...

Chlorophyll fluorescence analysis: a guide to good practice and understanding some new applications.

Journal of Experimental Botany, 2013
Chlorophyll fluorescence is a non-invasive measurement of photosystem II (PSII) activity and is a commonly used technique in plant physiology. The sensitivity of PSII activity to abiotic and biotic factors has made this a key technique not only for ...

Identification of senescence and death in Emiliania huxleyi and Thalassiosira pseudonana: Cell staining, chlorophyll alterations, and dimethylsulfoniopropionate (DMSP) metabolism [PDF]

, 2012
We measured membrane permeability, hydrolytic enzyme, and caspase-like activities using fluorescent cell stains to document changes caused by nutrient exhaustion in the coccolithophore Emiliania huxleyi and the diatom Thalassiosira pseudonana, during ...

AlphaFold‐Guided Bespoke Gene Editing Enhances Field‐Grown Soybean Oil Contents

Advanced Science, EarlyView.
An AlphaFold‐guided method is developed to functionally optimize soybean sugar transporters and achieve bespoke gene editing of GmSWEET10a/b to improve oil content in an elite soybean cultivar in multi‐year, multi‐site field trials. The combination of AI‐guided protein design and gene editing may unlock a huge potential to improve the genetic trait de ...

Temporal and spatial variations in phytoplankton productivity in surface waters of a warm-temperate, monomictic lake in New Zealand [PDF]

, 2010
Surface phytoplankton productivity measurements were carried out in morphologically complex Lake Rotoiti with the objective of defining variations between sites and seasons, and the dominant environmental drivers of these variations.

The MdHB7L–MdICE1L–MdHOS1 Module Fine‐Tunes Apple Cold Response via CBF‐Dependent and CBF‐Independent Pathways

Advanced Science, EarlyView.
In early cold response, MdICE1L utilizes MdHB7L as a cofactor to facilitate the transcriptional activation of MdCBFs, thereby activating cold signaling rapidly and strongly. Subsequently, MdICE1L is degraded by MdHOS1. Meanwhile, MdHB7L is released and accumulates.
